摘要
目的:分析胃肠道穿孔的CT征象,提高CT对胃肠道穿孔诊断的准确性。方法:分析53例经手术病理证实为胃肠道穿孔的CT征象。对有无腹腔游离气体、腹腔积液、腹膜炎及胃肠道壁的改变进行观察、分析。结果:53例胃肠道穿孔的主要CT征象:腹腔内游离气体(71.7%),腹腔积液(84.9%),腹膜炎改变(60.3%),脓肿(7.5%),胃肠道壁的改变(56.6%)。53例中,CT诊断为胃肠道穿孔48例(90.6%),对穿孔部位的诊断符合率为67.9%,对穿孔病因诊断符合率为58.4%。结论:CT平扫能清晰显示胃肠道穿孔的主要征象,结合临床综合分析,有助于提高CT诊断胃肠道穿孔的准确性,包括穿孔部位和病因的诊断。
Objective：To analyze the CT findings of gastrointestinal perforation for improving CT accuracy of diagnosis. Methods： CT findings of 53 gastrointestinal perforation cases proved by surgery and pathology were analyzed. The free air in abdominal cavity, peritoneal effusion, peritonitis and gastrointestinal wall changes were observed. Results： The main CT signs of gastrointestinal perforation included： free air （71.7%）, fluid （84.9%）, peritonitis changes （60.3%）, abscess （7.5%）, gastrointestinal wall changes （56.6%）. The sensitivity of gastrointestinal perforation by CT was 90.6% （48/56）, Accurate judgement for perforated site was 67.9% and the accurate judgement of the reason was 58.4%. Conclusion： CT can clearly display the main signs of gastrointestinal perforation , combination with clinical data and CT signs is helpful to improve the CT diagnostic accuracy of gastrointestinal perforation and the judgement of the location and the reason.
